'How I Met Your Mother' Season 9 spoilers on 200th episode, why Ted tells the story to his kids and wedding songs

Brace yourselves, How I Met Your Mother fans, because we've got spoilers on not one, not two, but three Season 9 plot points, including the milestone 200th episode that airs in two weeks.

So let's start there. The "Matt's Inside Line" column at TVLine reports that the 200th episode will not only show The Mother's past, but also how her past intertwines with the history of the characters we already know and love:

"Episode 200 aka 'How Your Mother Met Me' will show what Cristin Milioti's character has been up to all these years, 'intersecting' her path at times with familiar past storylines. 'It's a fun little 'Disneyland tour' through the series, from the perspective of someone outside the group,' EP Carter Bays shared at the CBS sitcom's final TCA panel. 'It's very emotional, and we could not have done this with any other actress.' (Carter also said that 'some fun trickery' was used to drop The Mother into past episodes.)"

We'll hazard a guess and say that "fun trickery" means we'll see that The Mother has been in the background of key scenes throughout the series.

Next, TVLine reveals information about Robin's mother and an interesting note about Future Ted's telling of this nine-season story to his children:

"'There's an episode coming up about the fact that Robin's mom hasn't come to the wedding - and Lily really, really wants Robin to be upset about it,' EP Craig Thomas shares. 'Lily thinks Robin needs this emotional catharsis about this fact.' And speaking of mothers: By the series' end, we will learn that there is a specific reason why Adult Ted chose the time he did to tell the kids about how he met you-know-who."

Some fans have worried its because The Mother is deceased in the future, but we're hoping that's not the case.

Finally, a reader asked TVLine if The Mother would sing at the wedding on the show given Milioti's Tony nomination, and the site responded with the following:

"'There's a lot of live music coming up,' is all EP Bays would say on that topic. Added Thomas: 'Stay tuned!'"
